Levin Post Shop's postal services and bill payments facilities will move across the road to Paper Plus from April 11.
Paper Plus owner Bernie Wanden said offering post shop services is a natural fit for his store.
His won't be the first Paper Plus shop that goes into business with NZ Post.
"There is an established model that works well for both NZ Post and Paper Plus stores. We are used to handling substantial volumes of traffic and are long established local businesses."
NZ Post approached him with the idea of taking on that side of their business soon after it announced it wanted to separate postal services from Kiwibank in Levin.
